Open Economic & Quant Research Data

Versioned research data for CasualLab, Macroeconomics, Mortgage Rate Lock-In and Housing Market Dynamics, Tariff Incidence, Order Flow to Price Impact, Emerging-Market Factor Timing, Polymarket Cross-Sectional Factor Study, and Crypto Factor Zoo and Post-Publication Audit, including publishable data, fixtures, reports, and reproducibility documentation.

Project code, tests, and run configuration live in the GitHub repositories listed under Related resources. dataset_manifest.json describes the 8-project release.

Repository structure

CasualLab/: causal inference and policy-simulation research content.
Macroeconomics/: vintage-aware forecasting and public-source adapter research content.
RealEstate/: housing-finance research on mortgage lock-in, mortgage exits, local activity, prices, and construction. Registered loan-level records and loan-granular derivatives are excluded.
TariffIncidence/: official-data research on U.S. Section 301 tariff pass-through, sourcing reallocation, and domestic input-output propagation. Large raw, intermediate, analytical, and parquet result files are excluded from the public package.
Microstructure/: research-only market-microstructure protocols, reports, and documentation. Exchange observations, normalized or derived tables, fitted states, ingestion authorities, and generated run bundles are excluded.
EMFactorTiming/: emerging-market factor timing out-of-sample evaluation tables, JKP coverage metadata, and shrinkage benchmark reports across 21 emerging and 23 developed markets.
PolymarketFactors/: binary contract artifact funnel tables, price-neutralized factor IC summaries, category reversal diagnostics, and sample market fixtures.
CryptoFactors/: equity-to-perpetual factor transfer tables, a Benjamini-Hochberg FDR demonstration on a 10-date sample fixture, post-publication out-of-sample decay diagnostics, and sample perpetual panel fixtures. Published long-short tables charged about 2.5 bp per side instead of the stated 5 bp; see the project README's cost erratum.
dataset_manifest.json: file counts, exclusions, and release metadata for the 8-project release.

Supported uses

Reproducibility review, economics and quantitative-method research, public fixture exploration, and development of documented derivatives. The repository is not a single homogeneous machine-learning table; inspect each project README and schema before loading files.

Sources and processing

Each project retains its own provenance notes. Raw third-party sources remain subject to provider terms. Local Python environments, package installations, caches, bytecode, and operating-system metadata are excluded because they are not research data.

Licensing

Project-owned fixtures and documentation follow project-local terms; code terms are in each GitHub repository. Third-party data and dependencies retain their original terms. Inclusion in this versioned mirror does not grant a new license. Assets without confirmed redistribution terms remain marked RIGHTS_UNKNOWN in the observatory governance records.

Limitations

File types and schemas vary by project.
Some raw source rights require independent review.
Updated numerical comparisons are published only with benchmark and validation evidence.
Use a pinned Dataset revision for reproducible analysis.
